Chiara Nappi - Princeton, Nov. 16, 2002.

Chiara R. Nappi is an Italian physicist.

She obtained her Ph.D in physics from the University of Naples in 1976. She then moved to the United States of America to carry out academic research. Currently she is a professor of physics at Princeton University, Department of Physics and at the Institute for Advanced Study located in Princeton, New Jersey. Chiara Nappi has carried out research on various aspects of theoretical particle physics, mathematical physics and string theory.

Chiara Nappi was originally interested in constructive quantum field theory and rigorous statistical mechanics. Her research interest soon moved to skyrmion description of nucleons, interface of particle physics and nuclear physics, and string theory. In string theory, she focussed particularly on low-energy effective actions and their solutions. In her studies, she investigated the consequences of boundaries and higher loop corrections on the string effective actions through deriving Born-Infeld and Fierz-Pauli lagrangians from string theory. Later on, she worked on finding black hole solutions especially in two dimensional string theory. Currently Dr. Nappi is looking for connections between black hole solutions in two and higher dimensions and their apparent relation with AdS/CFT correspondence.

Chiara Nappi is married to Edward Witten, a famous mathematical physicist, Fields medallist, professor at the Institute for Advanced Study and founder of M-theory.

One of the major contributions of Nappi to modern astrophysics was the use of the Yang-Mills theory’s Yang symmetry to D=4.

Nappi was deeply involved in finding a relation between approaches to integrability in the Superconformal Yang-Mills theory.

Her contribution to the five-brane analysis has also been of remarkable importance. In massless states of matter, Dr. Nappi analysed and developed gauged and ungauged WZW models (the WZW models being on a non semisimple group).

Concerning duality, Nappi carried out studies on marginal perturbations and gauging.

Nappi’s contribution, through key academic papers, to the analysis of the two-dimensional black hole thermodynamics, should also be mentioned. She has also carried out research on charged black holes in two-dimensional string theory.

Together with her husband, Prof. Ed Witten et al., Dr. Nappi used the string theory on the closed, expanding universe model. In her studies, Dr. Nappi applied closed string equations of motion.
